NUKE COMP TIPS

Compositing is a big part of FX work, and so this section focuses on compositing tips in NUKE, a standalone program used to composite 3D renders and live-action plates.

As of writing, my Nuke version is 15.1

Using the PLUS mode to blend LIGHT-BASED FX

FX like smoke, transparent water or lightning, will benefit from the PLUS mode of merging becausde their alpha channels are not fully solid (1), rather they are more translucent. By using plus, we are extracting the alpha and merging it with the other elements, rather than putting one element on top of one another.

Naming files accoding to render or export sequence

When writing to disk, you can add the extension: %04d at the end of the file name to have the sequence chronologically referenced at the end of each file.

e.g. RENDER_001.exr, RENDER_002.exr, etc. = RENDER_%04d.exr
